# std::experimental::atomic_shared_ptr<T>::store

From cppreference.com
< cpp‎ | experimental‎ | atomic shared ptr

void store( shared_ptr<T> desired, std::memory_order order = std::memory_order_seq_cst ) noexcept; |  |

Atomically replaces the current value with `desired`. Memory is affected according to the value of `order`.

`order` must be one of std::memory_order_relaxed, std::memory_order_release or std::memory_order_seq_cst. Otherwise the behavior is undefined.

### Parameters

desired | - | the `shared_ptr` to store into the atomic variable
order | - | memory order constraints to enforce

### Return value

(none)

### Remarks

All changes to the `atomic_shared_ptr` object itself, and all associated `use_count` increments, are guaranteed to be performed atomically. Associated `use_count` decrements take place after the atomic operation, but are not required to be part of it. Any associated destruction or deallocation operations take place after the atomic operation and are not part of it.
